Ladies and Gentlemen,
Everyone knows I'm a big fan of these cars, and get into the "Black Magic" of these cars. The black magic is transmissions, and I get into the Blacker of the electronic transmissions(722.6).
Like I have said before, the easiest transmission to DIY for the first time is the 722.6 because it does not require mechanical adjustments. No vacuum controls, and no brake bands to deal with... Just a lot simpler
Here is piece of great literature to determine how worn-out your 722.6 transmission(any 722.6) it is based on how many cycles it takes to pressurize the clutch pack, and when a clutch pack is pressurized a gear is engaged, but no clutch pack equals to a gear ratio, but a combination of two or three clutch packs form a gear ratio. The gear ratio truth table document will give the decoding information on which clutch pack does what. The clutch packs are labeled K1, K2, K3, B1, B2, and etc...
The way one can determine "How worn-out" is the transmission is Mercedes Star must be used, and the car must be driven to get these values. The values go from 0-15-Zero meaning new transmission, and fifteen being flat out worn out. The last two paragraphs sumerizes this on the adaptation information, and I included data of a 100,000 mile M120 W140, and one can determine how worn the clutch packs are worn...
Though most say get a PPI, this is what the PPI data spells out...
Hope it helps,
Martin
